Material EasySet Library

For most materials, you can get built-in settings in XCS software. You can just apply them in one click.

1. Choose the material and confirm.

2. Choose settings according to your hardware and all software settings will be applied automatically. (power, speed, following height, etc.)

3. After clicking the process, you will get the recommended value. Manually adjust the focus position.

• For detailed settings, you can visit the link. (same as the XCS EasySet)
• For parameters for carbon steel thicker than 5mm, please contact the support team for help.

How to Adjust Settings

Impacts of different parameters

Parameter		Definition	Range	Test Step	Effect	Rule
Power		The size of the laser power determines the energy density and processing capacity of the laser	10%-100%	50%-75%-100%		Under the same parameters, the lower the power, the weaker the energy, the worse the cutting effect, and the material cannot be cut through
Speed		The speed at which the laser head moves on the surface of the processed material; the slower the speed, the more intense  The longer the light acts on the material, the more obvious the processing effect is	1-400mm/s	10-50-100-200-400		Too slow speed leads to large heat affected zone and local burrs, while too fast speed leads to non-penetration
Focus		Distance from the focus of the welding torch to the upper surface of the base metal (positive defocus on the upper surface of the base metal and negative defocus inside the base metal)	-12~+25	-4~-6~-8~-10		Normally, the thicker the plate, the more negative focus. If the negative focus is too low, there will be burrs. If the negative focus is too high, the plate cannot be cut through. Select the appropriate focus
Gas pressure		Pressure of the auxiliary gas at the nozzle outlet	0.05-1.2Mpa	0.6-0.8-1.0-1.2		The lower the air pressure, the worse the slag discharge capacity and the worse the cutting effect
Following height		The vertical distance between the cutting nozzle and the workpiece surface during laser cutting	0.3-1mm	0.3-0.5-0.7-1		The higher the following height, the worse the gas concentration. After the high pressure gas is dispersed, the slag cannot be effectively discharged. Therefore, the higher the following height, the more slag is hung.
Gas type		Laser cutting gas refers to the gas that is ejected through the nozzle (coaxial or lateral to the laser) into the cutting area during the laser cutting process	Nitrogen, Air, Argon, Oxygen	-	-	When cutting stainless steel with nitrogen or argon, the cross-section will appear whiter and brighter, while cutting with air may result in some oxidation and a darker appearance.  Refer to the gas suggestions for different metals
Duty cycle		The ratio of the actual working time to the total time of the laser in a working cycle	1%-100%	20-40-60-80-100		When the duty cycle is too low, it cannot cut through.
Frequency		The repetition frequency of the laser wave, the number of round trips of the wave per unit time	500-5000	100-500-1000-2000-3000-4000-5000		Due to the characteristics of the continuous laser, it is useless to change the frequency separately when the duty cycle is 100%, so the effects are basically the same. When the duty cycle is not 100%, it is found that the lower the frequency, the rougher the cross-section, and the higher the frequency, the finer the cross-section.
Perforation parameters	Perforation power	Laser output power during the piercing phase	11%-100%	20-40-60-80-100		The lower the power, the greater the probability of perforation failure
	Perforation time	Time of laser continuous action on one point	10-5000ms	10-100-500-800-1500		The lower the perforation time, the greater the probability of perforation failure
	Perforation height	Distance between nozzle and material surface during piercing	5-30mm	5-10-15-20-30		The higher the height, the greater the splash and the larger the perforation diameter
	Perforation duty cycle	Percentage of the on-time of the pulsed laser in the entire cycle	50%-100%	50-70-90-100		The higher the perforation duty cycle, the greater the perforation splash and the larger the perforation diameter
	Perforation frequency	Number of laser pulses per unit time	50-5000	50-500-1000-1500-3000-5000		No obvious difference, need to adjust with duty cycle
	Perforation delay	Refers to the time interval between the start of the laser piercing and the start of the cutting head movement	0-1500ms	200-500-1000-1500		The longer the delay, the higher the stability
Soft-start		1. For some thick materials, after adding the lead-in lines, if there is slag hanging or overburning, you can add the slow start parameter.  2. Soft-start function will start cutting slowly at a slower speed at the beginning of cutting to ensure cutting quality of the latter part of the figure.  3. After adding lead-in lines, XCS software will apply the settings of soft-start height, speed, distance automatically, there is no need to adjust.				Soft-start cutting for thick plate can reduce the bad cutting caused by splash during perforating.
Flying cut		1. Setting multiple circles or rectangles with the same parameters, size, and shape and arranged regularly as fly-cutting can significantly improve the cutting efficiency.  2. After setting fly-cutting, do not modify the fly-cutting graphics, which may cause the fly-cutting effect to fail.			-	Turn on fly cutting to reduce processing time and optimize efficiency. It can only be used on thin plates.

Adjust Parameters Based on Cutting Effects

• Check the current gas pressure — Make sure it meets the required
  Ordinary nozzle: 1.2 MPa, SaveGas Nozzle (Telescopic Nozzle): 0.6 MPa

Sample Image	Troubleshooting	Possible Cause	Adjust Settings
	Localized blackening of the cutting surface: not cut through	Cutting speed too fast or focus too low	Reduce speed, or raise the focus position For example, if the current focus is -4, try changing it to -3 or -2.
	Single-sided slag	Laser is off-center	Check if the laser beam is aligned to the center.
	Hard slag	Hard dross on the bottom indicates focus is too high	Lower the focus further (negative direction). For example, if the focus is -2, try -3 or -4.
	Normal, the cutting edge is clean.		No adjustment needed.
	Soft slag	Focus slightly too low	Raise the focus slightly.
	Layered cut surface	Focus is too low	Raise the focus.
